Cleaner leaving an anti-microbial film

Abstract

A surface having a anti-microbial film is disclosed having a dried film on the surface comprising an optically active isomer of a monoester of glycerin and a C 6 to C 22 aliphatic acid having antimicrobial activity. A composition for cleaning and inhibiting microbial growth on surfaces includes an emulsion having at least a cationic soap and the monoester. A method for cleaning and inhibiting microbial growth on surfaces is also disclosed that includes providing a mixture of the soap and the optically active isomer of a monoester of glycerin and a C 6 to C 22 aliphatic acid having antimicrobial activity, making an aqueous mixture of the mixture and applying the solution on the surface to be cleaned. Preferably the monoester includes at least one of monolaurin, monocaprin and monomyristin.

1 . A concentrated cleaning composition for inhibiting regrowth of microbes on surfaces comprising: 
 an emulsion comprising    a cationic soap; and    a monoester of glycerin and a C 6  to C 22  aliphatic acid.    
   
   
       2 . The composition of  claim 1  wherein said monoester comprises at least one of monocaprin, monolaurin and monomyristin.  
   
   
       3 . The composition of  claim 2  wherein said monoester comprises monolaurin.  
   
   
       4 . The composition of  claim 1  further comprising an amphoteric soap.  
   
   
       5 . The composition of  claim 1  further comprising a chelating agent.  
   
   
       6 . The composition of  claim 5  wherein said chelating agent is at least one of ethylenediaminetetraacetic acid and ethylenediamine disuccinnic acid.  
   
   
       7 . The composition of  claim 1  further comprising a solvent for the monoester.  
   
   
       8 . The composition of  claim 1  wherein said emulsion is a microemulsion.  
   
   
       9 . A method for cleaning and inhibiting microbial growth on surfaces comprising: 
 providing an emulsion of a cationic soap and a monoester of glycerin and a C 6  to C 22  aliphatic acid;    adding water to the emulsion form an aqueous solution; and    applying the solution to the surface to be cleaned.    
   
   
       10 . The method of  claim 9  wherein said providing step further comprises dissolving the monoester in a solvent and adding at least one of a surfactant and a soap.  
   
   
       11 . The method of  claim 10  wherein said providing step further comprises saponifying the monoester with a chelating agent.  
   
   
       12 . The method of  claim 9  wherein said applying step comprises brushing, screeding, spraying, rolling, wiping or spreading.  
   
   
       13 . The method of  claim 9  further comprising emulsifying the mixture.  
   
   
       14 . A surface having a non-persistent anti-microbial film comprising: 
 a surface; and    a dried film on said surface comprising a monoester of glycerin and a C 6  to C 22  aliphatic acid and a cationic soap.    
   
   
       15 . The surface of  claim 14  wherein said monoester comprises at least one of monocaprin, monolaurin and monomyristin.  
   
   
       16 . The surface of  claim 14  wherein said film further comprises an amphoteric soap.  
   
   
       17 . The surface of  claim 14  wherein said film further comprises a soap.  
   
   
       18 . The surface of  claim 14  wherein said surface is an inanimate surface.  
   
   
       19 . The surface of  claim 18  wherein said surface comprises at least one of wood, plastic, paper, leather, glass, drywall, ceramic and metal.  
   
   
       20 . The surface of  claim 19  wherein said surface comprises drywall.  
   
   
       21 . The surface of  claim 14  wherein the monoester in said film is saponified with at least one of ethylenediamine tetraacetic acid and ethylenediamine disuccinate.
